- goggles as a protection against extreme heat to the eyesight, such in certain lines of employment, as a protection against certain rays of light injurious as violet rays and the light tending to produce. occupational diseases of the eye, etc.

The objects of the present invention are to provide in a commercially practical form a goggle structure adapted to be. made out of material that is a poor conductor of heat, such as wood or fibe. to provide a structure that is light in weight and one that eliminates face-contacting metal parts; to provide for comparatively inexpensive and convenient renewal and eachangeability ol the ditlerent parts, so that when one section or part of the goggles as a wl'iole is broken or damaged it may be quickly and cheaply replaced without loss of the sound portions of frames or lenses, and to provide these improvements in a structure which, as a whole, is as neat and pleasing in. general appear once as more expensive structures having special regard for that feature.

ll ith the above-named general objects in view this invention consists in the novel con-- struction, combination and arrangement of t is a perspective portion of one of the hmged sections showparts, all illustrated in the accompanying drawing and more particularly pointed out in the appended claims.

.ln the drawing, Figure 1 is a perspective view of a pair of goggles embodying my in-- vention. Fig. 2 is a perspective view of one of the two identical lens frames, with its parts of main frame, shield and lensho-lding frame or ring, and lens separated. Fig. is a side elevation, partly in section, and partly broken away, of. my invention. Fig. view ot'a broken away mg the manner in which the hinge leaf is embedded in and connected with the non-metallic body. Fig. is a section taken substantially on line 5 ct Fig. 3.

.the material of which the made, all materials adapted for the present purpose having sufficient purpose. However, as will hereinafter apas hereinafter described in detail,

Referring in. detail to the several views, the present invention is shown embodied in the hinge type-of goggles, which embodiment includes improvementsinthe hinge connection for two main frames '2 and 3 which are substantially identical so that a description of the parts of one practically describes both. The members 2 and'3 are flat disks of fiber, or othcrmaterial suitable for the purposes hereinafter more fully set forth, and each ofthese disks has an opening 4 therein which forms a ring with ends and 6 which make it anopen ring. In Fig. 2 the ends 5 and 6 are shown forced apart for the sake of more clearly showingconstructi'on, but they are normally in contact with each other as in Figs. 1 and-3 and when forcibly separated to a limited extent are returned to normal b I the elasticity of parts 2 and 3 is elasticity for that pear, elasticity in the material. is not the sole reliance that the ring"remain substantially closed. c

in the opening at, or against the wall j-7-' thereof, is placed a fiber or heavy paper ring; 8, which is also a split ring and has as lntegral part thereof a curved a, preferably, sideshield portion 9 with ventilation holes 10 therein.

the ring 3. Hence the parallel sides of the The groove 11, as shown, is anexterior groove. Opposite an outer flange 12 produced by the formation of the groove .11 is an interior groove 13 that is of sullicient width to receive the circumferential edge -1elof a lens 15 of suitably colored or transparent material, according to the particular aitisanship in which the goggles are employed. Vl here eye-straining lights are encountered and these are of various colors the coloring of exchangeable lenses will be such as to counteract the normal effect of the eyestraining light. l6'and 17 represent the ends of the ring 8 which are also nor mally in contact and forcibly separated in i g. 2 to clearly locate the relative positions grooves 11 and 13 and flanges l2 and 16 formed by the groove 11, the flange 16' being extended into the shield 9 along a portion of the periphery of the ring 8.

In the ring 8 is a groove 11- the bottom of which is engaged by the inner periphery 7 of qroove l1 en 'a e oppositeside's of the body 3. b D

plain glass or other As shown in Figs. 2 and 3 in a simple and unobtrusive form provision may be made to positively hold the ring portion of the body 2 or 3- closed, or to hold the ends 5 and 6 in contact with each other. For this purpose lugs 17 and 18 are shown projecting inwardly from the'wall 7 at the ends 5 and 6. The lug 17 is snapped into a recess 19 and the lug 18 into a recess 20. The lug q-labeled 28 and are held together by a usual pintle 29. To securely fasten these leaves against longitudinal movement in their seats 24 and 25 and agalnst outward movement in 'a horizontal direction the outer edges of the leaves 26 and 27 are provided with thin bars 30 and 31 which engage slots-32 and 33 arranged at right angles to the slots and 25 and project beyond the ends of the leaves as shown best in Fig. 4. The projecting portions are bent over the bodies 2 and 3 and form holding clips 3%. and 35 on one leaf and 36 and 37 on the other leaf. This obviates the use of screws. lithe leaves 26 and 27 are regarded as a single flexible connection their function-would be the same so far as their connection with the parts 21.

and 22 is concerned.

1 ,ao'neee I claim as my invention- 1. A pair of goggle lenses cmisisting of non-metallic disks having openings for lens frames cut therein and farming expansiblc -open rings, and lens frames having lenses therein, said lens frames being arranged to be held in said open rings.

2. A pair of lenses consisting of a pair of fiber disks connected together and forming main frames, said main frames having meeting ends normally mcetin g and forming expansible rings which may be opened to insert therein lens-carrying frames, and lens-carrying frames held in said rings.

A. pair of goggles consisting of main frames connected to move angularly relatively to each other and forming split rings which may be expanded to engage and hold lens-carrying frames, and lens-carrying frames consisting of grooved rings which are expansible to engage and hold lenses.

l. The combination in a pair of goggles of split ring main frames, and split ring lens-frames, the former engaging the latter and the latter adapted to engage lenses, and means for preventing relative movement of lens frames and lenses, and main frames and lens frames.

A pair of goggles consisting of a. pair of pivoted together frame members having lens-frame portions which are substantially split rings, split ring lens holders or lens frames having means thereon to support lenses therein, and means for holding the first mentioned split rings closed against accidental expansion.

In testimony whereof I have hereunto signed my name.
